Exhaust help

[Beto08]

Whats the best exhaust for my 03 v8 4.6L screw? Also what size?

[DarrenWS6]

2.5" for true duals, 3" single, or single in with a 2.5" outlet muffler. Magnaflow sound great on these trucks. Look up F150 exhaust videos on youtube. The most prefered cat-back is the Roush Off-Road.

yep the roush offroad's sound amazing or magnaflows are gettin about as popular as flowmasters are

also don't forget about the dynomax race bullet!

Just realized my mistake, you said 2003, Roush does not make exhausts for that style. But none the less your best bet if buying your prefered muffler and tip(s) and having a shop install them for a lot less than the price of an average cat-back.

x2 saves you alot of money just buying a muffler and buy tips from the shop unless you want ss magnaflow tips or something else, as far as chrome tips just go to the shop and bring the muffler you bought off the internet and get him to install it

Well first off I'm confused by your claim, you have a 14" Flowmaster? Flowmaster does not have a 14" length muffler, they have a 13" which is the 2 chamber mufflers, and Magnaflow has a 14" length muffler.

Either way it will sound good.

No problem. Do you happen to know the model Flowmaster you have? If its a 5x9.50x13 its most likely a 40 series, or if its 4x9.75x13 its the Super 44.
